This series is shot blast machine of pipe steel tube with maximum, medium and minimum type and cylinder for roller feed, and it mainly uses high-speed shots thrown by blast wheel of high effectiveness and strength, and impacts scale, rust layer, and other impurities on the surface of steel pipe so as to make it obtain refined and bright surface and improve pull-resisting and press-resisting strength of the worpiece surface with certain surface rough degree, which could improve adhesive strength for protection of surface paint residue and be helpful to improve paint quality of steel tube, reaching the purpose of corrosion-proof, protecting tube and extending use life of steel tube.shot blast machine.
